Can't cancel render

In certain circumstances, like a high-load render, pressing the Cancel Render button does not stop the rendering process. The project render queue reports Stopped, but you can see the playhead continuing down the timeline. I often need to quit the entire program, where I get a 'do you want to stop render and quit' warning/message. When I click stop render and quit there, DRS closes immediately.

Consider including a system spec in your signature to assist troubleshooting, indicating Resolve version, operating system, and computer spec (including GPU and driver).

If the host hangs or crashes, please include a link to diagnostic logs. Instructions to generate logs are provided in the FAQ: viewtopic.php?f=21&t=90190#16

It sounds like the system is so overloaded everything is behind. How long did you leave it?

Done.

System is otherwise fully responsive. System spec doesn't matter: stop means stop.

This has looooong been an issue for Resolve.

Yeah, I've seen this happen. My guess is that it's queued up a whole bunch of files in the buffer, and it just can't instantly slam the door shut and stop the train from going down the tracks. I have particularly seen this in what you call a "high-load render" (or what I'd call a big, bulky render with a lot of effects and titles and tons of source material).

One thing I do is this: before I render a big mofo project, I'll render out some :30 second tests just to make sure everything is fine -- resolution, aspect ratio, audio track assignments, slates, versions, color space, burn-ins, and so on. Once I verify that everything is kosher, then and only then do I hit the big switch and let it render out the whole show, which could take an hour or two.

I realize this doesn't solve your problem, but it is a method for avoiding the need to stop in the first place. If you know everything is going well, then there's no need to stop the render.
